Snapdragon 600 - GPU Performance

On the GPU side of Snapdragon 600 we're still looking at Adreno 320, which is easily Qualcomm's first highly competitive GPU. At its launch, Qualcomm claimed the Adreno 320 clocks in Snapdragon 600 could be higher than what we saw in S4 Pro/APQ8064. To find out, we turned to our trusty GLBenchmark suite.

The good news is that none of the thermal throttling we saw on the APQ8064 based Nexus 4 was present on the HTC One. Curiously enough, the thermald.conf file is now stored as a binary file - which means we can't get direct access to it. Either way, although the One can get warm during heavy CPU/GPU workloads, it doesn't throttle while running GLBenchmark which meant our freezer can remain on food cooling duties for this review.

GLBenchmark 2.5 - Fill Test

Here we see a small increase in fill rate compared to the Nexus 4, roughly 14%.

GLBenchmark 2.5 - Fill Test (Offscreen 1080p)

The beauty of being on a 1080p display is that GLBench's on and offscreen tests produce roughly similar results as they are both run at 1080p. The offscreen results do have vsync disabled though.

GLBenchmark 2.5 - Triangle Texture Test

Very similar triangle throughput to the Nexus 4, and a bit lower than the Nexus 4 freezer test, which implies that Qualcomm is doing a better job of keeping GPU clocks under control in Snapdragon 600.

GLBenchmark 2.5 - Egypt HD

The "game" benchmarks in GLBench give us a good indication of overall performance. The offscreen results are most interesting from drawing comparative conclusions:

GLBenchmark 2.5 - Egypt HD (Offscreen 1080p)

The One is fast - it's now the fastest smartphone we've ever tested in the Egypt HD offscreen test. The margin over the Nexus 4 however makes me believe that we're talking about very small increases in GPU frequency at best (either that or better thermal management).

GLBenchmark 2.5 - Egypt Classic

GLBenchmark 2.5 - Egypt Classic (Offscreen 1080p)

The Egypt Classic results are equally impressive. Here we're seeing about a 12% increase in performance compared to the APQ8064 based Optimus G, so at best we may be talking about a 15% increase in frequencies - or again, just better thermal management (or a combination of the two). Given the fact that process node hasn't changed at all, I think a small clock speed boost wouldn't be unreasonable to expect from the 600's Adreno 320. It's very clear that thermal management has improved though.

    Just one point on why there isn't enough analysis of UI. This is Anandtech, a site built on review of hardware, which began with reviews of motherboards. Software and UI is really not the main focus of Anandtech. Hardware and Build, whether as in the external aluminum case, or in the internal SoC, are the main (and strong) suits of Anandtech and their reviews. Reply

    I would direct you to the reviews of Surface or iPad Mini or any number of similar UI/Hardware products. That detail is at least approached in those reviews. I'd agree hardware is the comfort zone here...but it certainly isn't the only element reliably addressed. Until this review. Reply

    This was an awesome review. I look forward to the S4 review and then a comparison to the HTC One. Great article!! Reply

    Black one is aluminum. Some say it is anodized, some say it is painted. Any case, it smears and scuffs for sure.

    I'm with superflex on this one. I have an iPhone 3G that has been in constant daily use for over 4.5 years now on the original battery. A decent quality lithium-polymer battery can manage 800 charge/discharge cycles while retaining 80% of its original capacity, which would be 2.2 years even if you discharged it fully once a day.

    If your battery won't hold a charge anymore, you replace it. If you're squeamish about doing so because you bought a sealed $800 smartphone with no user-serviceable parts, then either pay for extended warranty coverage or just take it to someone who knows how it's done.

    Thanks for a fantastic review on the HTC One. I'm not sure I have a reasonable idea of how much work really went into this, but I'm guessing it was even more than I think, which is a lot. I probably learned as much about how to compare phones as I learned about the HTC One itself. Reply

    I already pre-ordered this HTC One, but today I went to the store to check it out. I must say I am kind of disappointed in the build quality. The seams where the screen and the aluminum meets were not even on the four corners. I hope mine is completely flush.

    This is one of the reason I returned Surface, not exact problem but similar. The screen on Surface was wobbly on the bottom center edge where the Windows soft key is. I don't think many people noticed or care though and I'm just being an ass on quality aspect.

    Well I did this the other way around...

    I went to the store first, checked the build quality, and THEN bought one. Seemed lovely to me.

    ...Despite how much I wanted removable battery and microSD slot.

    Oh well...

    Great review. I have this phone and I am quite pleased with it. Can someone tell me if the glass covering the camera on the back scratch resistant gorilla glass please? Can't seem to find this information anywhere and it looks like the glass covering the rear camera already has a few tiny blemishes even with careful use. Thanks in advance Reply
